Sufficient Precision

ABSTRACTInelastic neutron scattering measurements of the atomic momentum distribution, the atomic kinetic energy and other single atom properties in quantum liquids and liquid neon are presented. The data were taken on the MARI instrument at ISIS and analyzed using a new method. The measurements have sufficient precision to show that n(k) in a normal Bose liquid differs significantly and unambiguously from the classical, Maxwell-Boltzmann distribution. The final state broadening function is also extracted from the data and found to be similar in liquid 3He and 4He.

Abstract Using deep inelastic neutron scattering, direct measurements have been made, i) of the dynamic structure factor of a series of condensed argon samples over the temperature range 18 to 85 K, near melting (for wave-vector transfers 12 to 26 Ä -1) and ii) of liquid neon, near 27 K (for wave-vector transfers 10.4 to 27.6 Ä -1). Neutron time-of-flight chopper spectrometers were employed. Single-particle kinetic energies, £ k , can be obtained from the analysis of the Doppler-broadened recoil spectrum of the target particles. For argon the temperature dependence of £ k can be compared to expectations from theory, from thermodynamic data, and from previous neutron scattering measurements on collective vibrational modes. For liquid neon the wave-vector-transfer dependence of J{y), the longitudinal momentum distribution function, is being analyzed for final-state effects.
